COMMODORE T. PEIGLER, OF GREENVILLE, SOUTH CAROLINA.

- ROTARY ENGINE.

Specification of Letters Patent.

Patented Sept. 3, 1912.

Application filed January 3, 1912. Serial No. 669,275.

To-all whom it may concern.

Beit known that I, COMMODORE T. PEIG- LEE, a citizen of the United States, residing at Greenville, in the county of Greenville and State of South Carolina, have invented certain new and usefulImprovements in Rotary Engines; and I do hereby declare vthe following to bea full, clear, and exact description of the invention, such as will enable others skilled in the art to WlllCh 1t app-ertains to make and use the same.

My invention relates to improvements in rotary engines, and it consists in the constructions, combinations, and arrangements herein described and claimed.

An object of my invention is to provide a compact and powerful rotary engine adapted to operate efiiciently under the expansive action of steam or other actuating fluid.

A further objectof my invention is to provide an improved rotary engine adapted to minimize all leakage and condensation losses and to operate with a uniform driving force, or torque, under all practipal conditions.

In the accompanying drawings, forming a part of this application, and in which similar reference symbols indicate corresponding parts in the several views :-Figure 1 is a side elevation, with one side of the casing removed, illustrating one embodiment of my invention; Fig. 2 is a vertical,

axialsection of the construction shown in Fig. 1 Fig. 3 is an edge view'of the piston wheel and disks, with the spiral casing abutments. shown in their posit-ion relative thereto; Fig. 4 is a perspective view of a preferred form of piston disk; Fig.;5 is a detail section of a piston disk; and Fig. 6 is e; fragmentary section through apisto dis a r Referring to the drawings, l indicates the engine shaft rotatably mounted in a casing 2 and carrying a piston 3, which latter is provided with annular chambers 4 and 5 communicating, respectively, with a steam supply pipe 6 and an exhaust pipe 7. A series of radially arranged disks 8 are rotatably mounted by spindles 9 on said piston in engagement with the casin adapted to receive stationary abutinents 11 extending from said casing into engagement with the periphery of said piston 3; The piston 5 is provided with admission ports 2; Said disks'being provided with incline slots 10 12 extending from the annularsupply chamher 4 to the rear of each disk 8, and with exhaust ports 13 extending from the front of said disks to the discharge chamber 5.

A preferred form of packing for the disk 8 comprises packing members provided with radially-extendingportions 14 for the slots 10 and arc-shaped portions 15 which overlap on the disks periphery. The packing members are carried by rods 19 slidably mounted in guides 20 within recesses 21 in the disk, and yieldingly maintained in proper packing engagement with the abutments 11 and easing 2 by spiral springs 22 confined between said members and guides; counterbalance weights 23 beingipivoted at- 24 within the recesses 21 and connected to said rods 19, for preventing excessive pressure of the packing members under the action of said centrifugal force. This novel construction insures an efficient and uniform packing under all operative conditions, and

eliminates all danger of excessive friction losses and wear.

All steam leakage between relatively moving parts is efficicntly prevented by springpressed packing rings 17 engaging the sides of the piston 3, and packing members 18 on the inner edges of the stationary abutments 11.

From the above description, it will be clear that, as the piston disks 8 are carried around by the piston 3, said'disks will be rotated on their spindles 9 by the stationary casing abutments 11; thereby causing said disks'to engage the casing along spiral paths with a rolling motion, with a resultant minimization of frictional losses and wear.

In the operation of my IlDVBIltlOIl, steam,

or other actuating medium, admitted through the inlet ports 12 to the rear of the several disks 8 will be confined between the said several disks and the spiral easing abutments l1 engaged by the latter, thereby forcing said disks forwardly to drive the shaft 1 with a substantially constant torque.

It will be obvious that the actuating steam can be efficiently psed exp'ansively by any well known valve device, such as a ring j valve seated within the outer periphery of the annular admission chamber 4, or independent tappetvalves carried by the piston for each of the admission'ports 12.

I have illustratedpreferred and tory constructions, but changes could/ be.

made within the; spirit and scope off" my invention.

satisfacing, a piston rotatably mounted therein,

slotted disks rotatably carried by said piston in engagement with said casing, said piston bei provided with inlet and exhaust portfieading to opposite sides of said several disks, andspiral abutments extending from said casing through such slots into engagement with said piston.

2. In a motor, the combination 0'1? a casing, a piston rotatably mounted therein and provided on its respective sides with an-. nular supply and exhaust chambers, slotted disks rot-atably'carried by said plston in engagement with said casing, said piston being provided with inlet and exhaustports' leading from said annular supply and exhaust chambers to the opposite sides of said.

several disks, and spiral abutments extending from said casing through such slots into engagement with said piston.

3. In a motor, the combination-of a casing, a piston rotatably mounted therein, rotatably mounted disks spaced equally on noa'aeaa said several disks, spiral abutments extend ing from said easing into engagement with said piston for providing a plurality of in- A dependent chambers about the latter.

4. In a motor, the combination of a casing, a piston rotatably mounted therein, disks rotatably carried by said piston in engagement with said casing and provided with radially-extending, axially-inclined slots, spiral abutments extendingefrom said casing through such slots into engagement with said piston, packing members extending within such slots and overlapping on the peri heries of said disks, and means for admittlng and exhausting steam at opposite sides of said several disks.

In testimony whereof, I afix my signature, in presence of two witnesses.
